TOLEDO, OHIO, A CORPORATION OF DELAWARE.

LOOK FOR wnmow Mommas.

Application illed larch 2a, 1920. Serial 170.96318.

The invention relates tolocks and refers more particularl to looks for use in window regulators to ho d the windowsin their various positions of adjustment. One of the objects of the invention is to provide a lock which is so constructed that it may; be cheaply manufactured. Another ob'ect is to provide a unitary structure inclu ing the lock and driving and driven members to facilitate mounting.

With'these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter. set forth.

In the drawings I I Fi ure 1 is an interior side elevation of a ve icle door, partly broken away, andshowing a window having a lock embodying my invention;

Figure 2 is an enlarged vertical section through the lock;

Figures 3 and 4 are cross sections, respectively, on the lines 3-3 and 44 of Figure 2;

Figure 5 is a plan view of a portion of the lock.

As illustrated in Figure l, 1 is a vehicle door having an opcnin in itsupper portion and a chamber in its Towerportmn for receiving thewindow 2 when lowered from a position closing the opening. 3 1s a window regulator for raising andlowermg the window and comprising the pivotal lifter arm 4, the crank 5 and suitable mechanism between the crank and the lifter arm for swinging the latter upon rotation of the former. This mechanism includes the rack 6, which is pivotally connected to the lifter arm, and the pinion 7 which meshes with'the rack and is adapted to be driven from the crank 5.

The crank 5 is secured to the drive shaft 8 as by means of the pin 9 extending transversely through the hub of the crank and the drive shaft. This pin is secured from accidentaldisengagement by means of the escutcheon 10, which normally extends over the ends of the pin and is ieldably heldin this position by the'upho stery ll-located upon the inner side of the door framefand in the present instance the lock board '12. The drlve shaft 8 is polygonal-shaped and is mill stock. The pinion 7 is preferably a stamping and is firmly secured between the washer 13 and the annular flange 14 of the bearing member 15, both the washer and bearing member being also formed preferably ot' stampings. In the present instance the ends of the teethof the pinion 7 extend laterally beyond the sides of this pinion and into corresponding recesses in the adJacent faces of the washer and bearing member so that the washer, pinion and hearing member'rotate as a unit. The ends of the pinion teeth Ina be made to extend beyond the sides of t e pinion by a coining operation.

The pinion 7 is in, axial alignment with the drive shaft 8 and is driven therefrom by -means of suitable irreversible drive mechanism located therebetween. This drive mechanism includes the hollow hub member 16, preferably formed of a stamping, which has the annular flange 17 rigidly secured to the outer end of the drive shaft and is provided with the opening '18 intermediate the ends of its cylindrical flange and the slot 19 of less width than the opening and leading from the opening longitudinally of the cylindrical flange to its outer end. 20 is a resilient coiled wire or coil spring surrounding the cylindrical flange of the hub member and having the inturned ends 21 and 22whichextend into the opening 18. 23 is a sleeve preferably formed of a stamping extending through and fixedly secured in the lock, board 12 and surrounding the coiled wire 20 and adapted to be engaged by the convolutions of thesame when expanded.

24 is a bearing memberpreferably formed of a stamping surrounding the inner end of the hub member 16 and having an axial portion 25 fitting upon the drive shaft 8 and a radial flange 26 located between the cylindrical flange of the hub member and the sleeve. This radial flange and the cylindrical flange 27 of the hub member 16 at the opposite end of the wire provide the space between the hub inember and the sleeve for'receiving the wire. 28 is a key member also preferably formed of a stamplng and having a projection 28 which is adapted to pass through the slot 19 and lie within the opening 18 of the cylindrical flange of the hub member 16, at which time it is located between the-inturned

ends

21 and 22 of the wire. This key member has at its inner end thestub shaft 29 and at its outer end the rivet: 3.05 the stub shaft ex di g axially into and being journaled in the outer end of the drive shaft 8 and the rivet 30 extending axially through the pinion 7 and the.

washer 13 and having at. its outer end the head 31 which cooperates with the shoulders 32 upon the key member to lirmly secure the washer 13, pinion 7 and bearing mem ber 15 together.

Tohold the parts in operative relation and. to form a unit thereby facilitating mounting, the sleeve 23 has at its outer end, the inturned flange 33 which abuts the outer face of the bearing member .15 and near its inner end the iii-rolled head 34 which is engageable with the radial flange 26 of the bearing member 24, whereby the, bearing members are held from movement away from each other and consequently the wire, hub member, key member and associated parts are held in operative relation. The sleeve 23 is also provided near its outer end with the outwardly extending radial flange 35 which is preferably formed by crimping and which is adapted to abut the outer face of the lock board 12. The inner end of the sleeve is provided with the outwardly extending turned-over flange 36 which rests against the washer 37 at the inner side of the lock board, this washer being one of a number of washers of different thickness and selected to compensate for various thicknesses of the lock boards.

The radial flange 17 of the hub member 16 is fixedly secured to the drive shaft by reducing the outer end of the drive shaft and sci-rating this reduced portion and then forcing the same through the opening in the radial flange. to form corresponding serrations therein. The outer end of the drive shaft is then turned over upon the radial flange to hold the latter from longitudinal displacement.

It will be seen that rotation of the crank 5 rotates the hub member 16 through the drive shaft 8 and one of the edges of the cylindrical flange of this hub member formed by the opening 18 engages one of the inturned ends of the coiled wire to contract the latter and move its convolutions inward- 1y away from. the sleeve 23. The inturned end is brougbtinto eTngagen'ient with the projection 28 upon the key men'ibcr 28 and this rotates this key member and with. it the pinion 7. The pinion being in mesh with the rack will therebyswingthe lifter arm. This operation holds true re ardless of the direction of rotation of thecriuik. I'Iowever, with the power removed from the crank and power applied to the pinion T to rotate the same, this pinion will through the key member '28 and one of the inturned ends of the coiled wire expand the coiled wire to firmly engage the sleeve to thereby prevent rotation of the pinion.

From the above description it will be read ily seen that I have provided a lock which is so arranged and constructed that its parts may be formed of stampings or mill stock thereby reducing the cost of manufacture. It will also be seen that I have provided a unitary construction including the irreversible drive mechanism or look and the drive and driven members.
